- Cloud maps: browse and play courses published by the community, straight from the course picker
- Search community courses by map name or author, sorted by hot, new or top rated
- All-time leaderboards alongside the seasonal ones, covering every run since launch
- Lobbies now advertise which community course they are running
- The spectator bar has been restyled to match the rest of the HUD, and moved to the bottom so it no longer covers the race timer
- Leaderboards and achievements now count official courses only, so installing a community map can no longer move the goalposts
- Changing course as the host left everyone else behind on the old one
- Other players saw a duplicated body when someone was ragdolled
- Changing course while somebody was still tumbling threw an error
- Achievements could unlock in bulk instead of being earned one by one
- Tour guide and Globetrotter became impossible to finish once a community course was installed
- Players joining mid-round were announced as having fallen off
- The Filthy rich achievement icon drew outside its badge and over the card above
- The lobby closed for everyone when the host left
- Community courses can only be picked from the menu: the host cannot switch to one mid-game yet
- Downloads show as in progress rather than a percentage, because s&box reports no per-package download progress
- Host migration is new. If the host leaves, the lobby should carry on with someone else, but do report anything odd
